You enter Death Valley by car mostly from the South, the only one of 4 sides where elevation is low. The weather pattern makes it so the wind almost never enters from the South. As moisture-laden clouds climb mountains they lose the moisture, it condenses into rain, and then most of the year you only see either clear skies or hopelessly dry clouds passing overhead when you're in the valley. Occasionally in August moist clouds come up (from the South) from Baja California and the deserts get afternoon rain. That hotel is at about 200' above sea level. To the east is a 5000' peak.
So, if you can get moist clouds in there and push them up over the mountains, weather happens.
